MEANS FOR ADJ'USIING STEREOTYPE :PLATES 0N PLATE GYLINDERS.

Application filed August 21, 19.20.v Serial No. 405,046.

To @ZZ whom it may con-cern:

Be it known that I, HENRY F. BEGHMAN, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Means for Adjusting Stereotype Plates on Plate Cylinders; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in stereotype plate printing presses and has particular' reference to the plate cylinder and means for attaching plates to such cylinder. j

The object of the invention is to enable a plate cylinder to properly carry plates slightly lvarying in length and to provide means to compensate for variations in the actual length of a stereotype plate due tok whether' or not the plates are cast from dry matrices or wet matrices. j i

It has been found that an ordinary newspaper-page stereotype-plate, if cast from a dry matrix, will shrink about one-fourth of an inch more than if cast from a wet matrix. Ordinarily the plate cylinders are made for certain size of stereotype plate, and if the stereotypers change from using wet matrices to using dry matrices, or vice versa, the plates do not properly lit and the cylinders haveto be rectiiied. Furthermore, ordinary plate cylinders are made for` a certain size of s-tereotype-page-plate, such as seven columns l-ems, or eight columns l-ems, etc.; and if the publisher wants to change the size of his pages it is very expensive and troublesome to do so, sometimes requiring remalring of the plate cylinders.

The prese-nt invention provides means whereby the plate cylinders can be readily adapted toaccommodate various sizes of plates cast either from wet or dry matrices.

For this purpose the plate cylinder isvpro-v vided with an adjustable but normally fixed plate stop or collar which, instead of being cast on or permanently secured to thecylinder, is radjustably mounted thereon as hereinafter described, and can be readily adljustedaccording to the size of plate to be `ence to the accompanying drawings, which illustrate one practical embodiment thereof, and when understood will enable others skilled in the art to readily adapt and use the invention.

In said drawings:

Fig. l is a plan view of one end of a j plate cylinder equipped with the invention.

Fig. 2 is apart longitudinal section and part side elevation of Fig. l. i

Fig. 3 and Fig. 3a are respectively an enlarged end view and an edge view of part of the reversible ring.

Fig. t is a detail partly sectional view indicating how the collar may be adjusted for a 7 -column IS-ems plate cast from a dry matrix.

Fig. 5 is a similar view showing the collar adjusted for a 7-column 13-ems plate castlfrom a wet matrix. r

Figs. 6 and 7 are similar views showing how the column may be adjusted respectively for an 8-column l-ems plate cast from a dry matrix (Fig. 6), or from a wet matrix (Fig. 7).

The cylinder l may be of any desired lrind or construction, such as is ordinarily employed in rotary web-printing presses, adapted to `carry stereotype plates. preferably shown as a single-page tubular Vplate adapted to carry single page tubular plates such as shown in my aforesaid patent. lihis cylinder is provided with the yusual groove lEL for engagement of the inner adjustable plate clamps (not shown) `adapted to engage the inner end of the plate lar adjustable and secure it in the desiredv position as hereinafter described.

As shown,the cylinder is provided near its outer end, whereon the collar 3 is ap- It is plied, With pluralityof` circumferential grooves; il?, which; are-intersectedrby fa-v long i.l`

ytudin-a-l'islet ilcfwhich may' merge into 'the-l outer end of the slot la and Jform a-co-ntin uationthereof, as indicated-'in the Adraw-- ings.;

' The groovesl'are adapted to receive a stop ring 2, which, is preferably made in two opposite. halvesso :that-fit` cam-loe :easily placed around the cylinder and inserted in the groove. The ringQE isof .slightlygneate er exterior diameter than the external diameten of the:H cylinder 1,. andvl lprojects? rout@ 'of' f of the vl.groove lbare adapted:'toflcehentered vided #with Tav projecting head' 4%', which: is'

It it should be'desired to cast such plate from a Wet matrix, the size of the plate would :befslightly greater' but the pressman could quickly prepare the platev cylinder therefor-by simply first releasing and removing the key 4, then slipping the collar 3 inward until the sections of ring 2 are freed; thenllifting out# 'such sections and" reversing them by--turningtlieln-` half around so that the' 'flange' 2f* will project toward "thel outer end'of4 the cylinder` and aavayfr'om tlie co'l`- lar Bb, instead ofl towardv thev collar (as linv lel grooves l1 and the ring 2 can be engaged with@ any one of* these grooves according'to the-length I'ofplate which it is desired: to accommodate".
